AS is great for pvpers cause it doesn't take too much skill to cap a hit on someone. Easiest fix to reduce the ganking, change the multipliers so it's harder to do so and give some profs that need AS to be effective at PVP an easier chance to cap......instead of adding some 3 sec stand still interruptable AS which is prolly going to be buggy from the get go. And instead of fixing it, you'll take another year to revert back to original AS.
Though SA/FA/AS locking each other out is fair I guess. But what's the matter with ganking? It's type of playstyle. Ganking setups usually sacrifice the long term survival, which is a fair trade off. Plus it adds more adrenaline to pvp instead of the slow-trade a few hits pvp you guys apparently have in mind. Fast paced pvp> slow paced pvp
